Review Meta Analysis
Effect of Perioperative Vitamin C Supplementation on Postoperative Pain and the Incidence of Chronic Regional Pain Syndrome: A Systematic Review and Meta-analysis.
Postoperative pain can contribute to increased risk for complications and lengthened hospital stays. The objective was to analyze the effects of perioperative vitamin C supplementation on postoperative pain and the development of complex regional pain syndrome I (CRPS I) in patients undergoing surgical procedures. ⋯ There is moderate-level evidence supporting the use of a 2 g preoperative dose of vitamin C as an adjunct for reducing postoperative morphine consumption, and high-level evidence supporting perioperative vitamin C supplementation of 1 g/d for 50 days for CRPS I prevention after extremity surgery. Additional studies are necessary to increase the level of evidence to determine the overall effectiveness and optimum dosage of vitamin C.

Meta Analysis
Transcutaneous Electrical Nerve Stimulation in Patients with Knee Osteoarthritis: Evidence from Randomized Controlled Trials.
Transcutaneous electrical nerve stimulation (TENS) has been reported to relieve pain and improve function in patients with knee osteoarthritis. The purpose of this systematic review and meta-analysis was to evaluate the efficacy of TENS for the management of knee osteoarthritis. ⋯ TENS might relieve pain due to knee osteoarthritis. Further randomized-controlled trials should focus on large-scale studies and a longer duration of follow-up.

Review Meta Analysis
Effects of Combining Dexmedetomidine and Opioids for Postoperative Intravenous Patient-controlled Analgesia: A Systematic Review and Meta-analysis.
This meta-analysis evaluated the effects of opioid-dexmedetomidine (DEX) combinations for postoperative patient-controlled analgesia (PCA). ⋯ These data suggest that an opioid-DEX combination is a safe and effective strategy for postoperative intravenous PCA.

Review Meta Analysis
Pharmacological and Combined Interventions to Reduce Vaccine Injection Pain in Children and Adults: Systematic Review and Meta-analysis.
This systematic review assessed the effectiveness and safety of pharmacotherapy and combined interventions for reducing vaccine injection pain in individuals across the lifespan. ⋯ Breastfeeding, topical anesthetics, sweet-tasting solutions, and combination of topical anesthetics and breastfeeding demonstrated evidence of benefit for reducing vaccine injection pain in infants and children. In adults, limited data demonstrate some benefit of topical anesthetics and vapocoolants.

Meta Analysis
Single-dose Systemic Acetaminophen to Prevent Postoperative Pain: A Meta-analysis of Randomized Controlled Trials.
The effect of a single-dose systemic acetaminophen to treat postoperative pain has been previously quantified, but the effect of systemic acetaminophen to prevent postoperative pain is currently not well defined. The preventive analgesic effect of acetaminophen has yet to be quantified in a meta-analysis. The objective of the current investigation was to evaluate the effect of a single preventive dose of systemic acetaminophen on postoperative pain outcomes. ⋯ Systemic acetaminophen, when used as a single-dose preventive regimen, is an effective intervention to reduce postoperative pain. It also reduces postoperative nausea and/or vomiting. Doses >1 g were not associated with greater reduction in pain outcomes.
